I’ve always preferred using nano over pico, and pico over vi, and vi for very low level file editing.
Anyway: nano for most things. But it’s not installed by default on Ubuntu 18.
And after getting a new VPS you probably have quite some configuration file editing to do, and in my blog posts I tend to say “and then just nano the file..”
Go ssh into your server with a sudo user.
ssh email@example.com -p 22
sudo apt-get install nano
Enter the accounts password and follow the on screen instructions. Once installed you can type nano -v to check if it’s actually installed.
Usually you can just type this to open a file
But to not wrap long lines, which sometimes can really help,
nano -w file.txt
I hope this helps you get started with how to install nano text editor on Ubuntu 18.
